...is it though? :-) Can a feature that hangs when presented with more
data than usual (however one defines that) be considered stable?

I'd say something "essential" is something you can't live without.  But
that doesn't seem to be the case here.  I could use Eglot over Tramp
with decent performance (although this is a local-to-local in disguise).
I wonder what Thomas has to say about performance with a real remote
server when he turns off ControlMaster.

Of course I do understand that it's a very sought after performance
optimization.  Doesn't seem to be quite finished, but that's just MHO.

Thanks.  I think that is a good start.  But can Eglot or the user
somehow set 'suppress' for connections "motivated" by Eglot, i.e. M-x
eglot in some remote file?  How?
